Why do people choose the Borg impulse? I've been planning my sets since I'll be hitting tier 4 soon and the bonuses the Borg impulse provide just don't seem to stack up against the likes of, say, the KHG engine.

What am I missing?

Honest question here.

I know feds don't get access to the KHG stuff, but what's so special about the Borg engine that people chose it so frequently?
